Degradação térmica e catalítica dos polímeros poli (acrilonitrila-co-butadieno-co-estireno) (ABS) e poliestireno de alto impacto (HIPS) oriundos de resíduos eletroeletrônicos
The high consumption level and wide diversity of electrical and electronic equipment available nowadays caused the signi cant increase of obsolete materials and waste, which can be harmful to the environment and health if discarded incorrectly. As a consequence, it is necessary to develop e ective …

Equilíbrio de fases de soluções polidispersas de polímeros
The thermodynamic description of macromolecular solutions is naturaly different from traditional approaches. In particular, molar mass distributions introduce significant qualitative and quantitative differences in the phase behaviour. Despite increasead efforts in the field, little is found in …
